domain of (x^2-16)/(4x^2)

domain

\frac{x ^{2} - 16}{4 x ^{2}}

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

d o main y = \frac{x + 1}{x - 3}

a sy m pt o t es f (x) = \frac{x ^{2} - 3 x}{x ^{2} - 2 x - 8}

d o main e^{x} + 2

a sy m pt o t es lo g_{10} (x)

r an g e 2 (x + 1)^{2} - 3
